Ingredients
- 50g unsalted butter, melted, plus extra for the tin
- 150g Oreo biscuits, crushed
- 840g cream cheese
- 100g pistachio creme
- 450ml double cream
- 250g caster sugar
- 3 tbsp cornflour
- 3 large eggs
- 2 tsp vanilla bean paste
- 2 (approx.) drops green food colouring (optional)
- 100g natural shelled pistachios, finely chopped
- 100g milk chocolate, chopped
Method
Step 1
Preheat the oven to 200°C/180°C fan/gas 6. Grease and line a 20 cm springform baking tin. In a bowl, mix the Oreos with the melted butter and a pinch of salt. Tip into the prepared tin and press into an even layer. Bake for 10 mins, then set aside to cool. Reduce the oven to 140°C/120°C fan/gas 1.Step 2
For the filling, combine the cream cheese, pistachio creme and 50ml of the double cream in a bowl with the sugar, cornflour, eggs, vanilla and 1-2 drops of food colouring (if using); beat with an electric whisk until smooth. Stir in most of the pistachios, reserving a handful for decorating.Step 3
Wrap a sheet of kitchen foil around the base and sides of the tin to create a water-tight seal. Pour the filling over the cooled Oreo base and smooth the surface.Step 4
Place the cake tin in a large roasting tray. Pour in enough boiling water to come halfway up the sides of the cake. Bake for 1 hr 20 mins or until set with a gentle wobble. Leave to cool for 1 hr, then chill for at least 4 hrs or ideally overnight.Step 5
Make the topping: put the chocolate in a heatproof bowl. In a pan, heat 100ml of the double cream until simmering, then pour over the chocolate. Stir to make a smooth ganache. Chill for 30 mins.Step 6
Release the cheesecake to a serving plate. Spread the ganache evenly over the top.Step 7
Whip the remaining 300ml double cream to soft peaks. Dollop on top of the ganache; scatter with the reserved nuts. Will keep chilled for 3-4 days.
